Irritrol RD600-INT-R Rain Dial 6 Station Indoor Remote-Ready Timer

In addition to the numerous upgrades built into this popular, long-standing controller, the optional CLIMATE LOGIC Wireless Weather Sensing System makes the Rain Dial-R a "smart" controller on the cutting edge of water management. When governed by Climate Logic, the Rain Dial-R will automatically water more on warm or hot days and less on cooler days. Applying the right amount of water to maintain a healthy landscape, the Rain Dial-R and weather-based Climate Logic Weather System seriously reduce overwatering and its expense.

  • 365-day calendar for Odd/Even date watering Meets the odd/even date watering mandates often used for landscape water reductions
  • Water well recovery (delay between stations) Option of pump circuit ON or OFF during
  • Master Valve/Pump Start circuit Assignable per station Stations requiring a booster pump can be supplied while other stations can run on street water pressure
  • Test All Stations program Allows a quick test of all stations from lowest to highest number

Does this timer have a setting for Odd/Even days? Setting for alternate days won't work because in a 31 day month there would be consecutive odd or even days.
jay c on Apr 9, 2012
BEST ANSWER: Actually, you set it to whatever day/days of the week you want it to turn on, so, you can do this yourself, there isn't a specific button that says odd/even. You choose on/off for each day.
I had a Rain dial RD 600 R put in my home to control my sprinklers and set to run on Tuesdays and Saturdays. It came on Thursday (today). How do I correct this?
A shopper on Jun 16, 2011
BEST ANSWER: It might be set on the wrong day. Turn the dial to current day, make sure the slide button near bottom is switched to "set" in the middle, and then if it is not on the correct day, use the + button to choose correct day. Return the slide button at bottom to "run" or "on" position, and dial to center for current time.
We need a key for our James Hardie Rain Dial controller, RD9000. Is the RD600 the correct key to order?
A shopper on Oct 31, 2014
is this new or refurbished?
Cary P on Aug 3, 2017
BEST ANSWER: I'm not sure why they referred this question to me, but this is new....They would have to specify if it was refurbished.....You may already know, but my experience is that this is the best control box you can buy.....To me, nothing compares.
Do you have rd600 with 4 valve?
Helen B on Mar 18, 2016
BEST ANSWER: I bought the RD600 last year to replace a very old Rain bird controller. It was easy to install and setup. It worked great all last summer and I'm about ready to turn it back on for this year.
It will control up to 6 valves, but I've only connected 4 right now. I plan to connect one more to water the flower pots on the deck this year.
I have an older model RD600 INT. I need the module replaced. Will this module work in my unit?
fred f on Apr 14, 2012
BEST ANSWER: I replaced my 10 year old unit with a new one and it worked perfectly.
Does the unit come with a transformer ?
A L on May 2, 2018
BEST ANSWER: It comes with a external xfmr, since it's meant to be mounted indoors. Exterior controllers have the xfmr mounted directly in the control box.
Are there online instructions for programing the controls?
Phil H on Jun 14, 2017
BEST ANSWER: I'm sure you can google a manual.. although they come with a manual and also there is a manual printed inside the unit on the back side of the zone location sheet. Hope this helps. These are great units and super easy to operate!
if my control unit is flashing its numbers what could be wrong? I have unplugged it from the electricity, I have unplugged the wiring harness to the unit, I have replaced the battery and 2 A fuse and it still is flashing and will not reset. The controller is 15 years old.
A shopper on May 27, 2017
BEST ANSWER: Its the troubleshooting code for that controller. The number on top and probably flashing FUS. Check the electrical path to the valve number that's flashing usually that solenoid or connection to it ihas failed. Try turning on the zone number that's flashing manually through the controller. If it doesn't come on, you have confirmed that's the issue
Change Number of Days?
Harry H on Jul 20, 2015
BEST ANSWER: Slide button at bottom from Off to settings or just set. Turn dial from current time counter clockwise to each day and make sure it says on for only the days you want. You will use the + or - button in top right corner to adjust for on or off. Then turn dial back to current time and slide button on bottom to the right from settings to run .
I cannot get the front zone to come on. Manually turning all the valves on one at a time won't do it. Every other zone can be manually operated.The daughter's new house and all, we have no point of reference. The unit may be the original or it may be 5-10 years old.???
Littljuan on Jun 25, 2015
Why does the unit run through the cycle and then start over again?
Fred M on Apr 15, 2014
BEST ANSWER: My guess is you have it programmed possibly unknowingly that causes this behavior. My exact same unit does not do that, it behaves just as I have programmed it.

Remember you can program A,B,C - so could it be that you have all three programmed all at different times and therefore appears that the system is starting over after one cycle?

Anyway go through all three A,B,C program modes make certain only A is programmed to run through all your stations 1 - 6. Make certain your starting times and days are correct.
I have a house with an existing Orbit model 57976 which is complicated for me to use. It's outdoor without a plug. Is there an Irritrol unit that does not require an outlet and can work with the electrical wires only? I have and own five Irritrol units that are installed on my house and others and find it very easy to work and control. Please advise? Vivian alcala
A shopper on Jun 20, 2013
BEST ANSWER: Hi, Richard here. Just purchased an Irritrol TC 6IN-R controller, the indoor enclosures have the external transformer requiring a plug, the outdoor enclosures have the transformer built into the enclosure, and uses the wires. They are 120 volt transformers and reduce the voltage to 24 volts for controlling the water valves at your stations. Also, this unit allows for remote programming, just disconnect the module from the enclosure, take inside your house, etc. and program the operations, then return the module to the enclosure, reconnect, and you are off! Hope that helps, let me know if you need to discuss further. Regards, Richard.
do you have a four station indoor timer?
Bradley B on Nov 4, 2012
BEST ANSWER: No. Irritrol does not make a 4 station unit. Home Depot has 4 station units by Orbit.
how do you set the control panel timimg?
A W B on Jun 28, 2012
BEST ANSWER: The question is not complete. This is a simple easy to set up timer.
Time of day. Put main control knob on Time of Day, put lower slider switch to set programs. Then us + and - to set time of day.
To set timing for each circuit. Put main control knob on #1. bottom slider switch to set programs. Then use + and - to set duration of time on for that circuit. Put lower switch to Run/Manual
To set time for the circuits to come on, set main knob to start time 1,2, or 3 (I only use #1). Put slider switch to set programs. Use + and - to set start time. Put the slider switch to Run/Manual.

Hope this helps. Jack
I have this already and it is not working/not sure why. If I get a new one and still does not work (could be wiring problem) can it be returned?
A shopper on Sep 7, 2011
BEST ANSWER: I too have a problem too. Lately I can not get rid of and an old program sequence. I needed to reprogram a new sequence. That worked just fine.
I erased the old sequence.It 'looks' like its gone but I keep getting watering on days I got rid of and nites at times I don't want??? How can I fix this? I am ready to go to a different brand. JOL
I have the 6 station model, of which I am using only 4 valves. am wondering if I can run stations 1,2 and 3 everyday, but run station 4 every other day?
tom b on Jun 28, 2019
BEST ANSWER: Yes, you can do this by setting up two programs, A and B, for example. You first would switch the "PROGRAM switch to "A". You then turn the dial to set the valve run time for stations 1,2,and 3. Then set one or more stat times for those stations. Then rotate the dial to each of the days, and use the up button to turn each of the days to "ON" . Then, rotate the dial to "SKIP DAYS", and set it to "01"-- that is, to run every day.

Now, to set station 4 to water every other day, switch the PROGRAM switch to "B". Proceed to set the run time for station 4. (You may check the other stations to be sure that no run time is set for the other stations on program B.) Then rotate the dial to "SKIP DAYS", set the number to "02". Because you have set this to water every other day, you will not need to set the days of the week.

The key to understanding this is that PROGRAM switch does not control which programs are to be run. The switch is for your use only during programming and when you wish to manually initiate the running of a program. In fact, all programs are active when the master switch at the bottom is switch to "RUN OR NORMAL". I do not know of a way to disable a particular, individual program.

I suggest reading pages 18 and 19 of the User's Guide. These pages describe using multiple programs, suggests a table to plan your programs, and gives some suggestions about using multiple programs.

All the best with this!
I need to replace an old Hardee HD-6100 controller. I tried a Rain Bird Simple-To-Set Unit and it didn't work. Any thoughts or suggestions? It's a 30 y/o Toro sprinkler system with 3 zones.
Dave F on Jul 13, 2017
BEST ANSWER: Irritrol Rain Dial 6 station is a quality product, not the big box store piece of equipment. It is a commercial/ industry based product that has given me years of trouble free service. Easy to wire & easy to program! Those extra zones would work well for garden & porch soakers.

I have an Irritrol RD 600 R with an error code 5En. What can I do to correct it?
virgilio f on Mar 1, 2017
BEST ANSWER: It looks like a 5 but it's an "S" .It's the rain sensor error code. Swing open the dial and look for the tiny black switch that reads rain sensor bypass. If you don't have a rainsensor hooked up, switch to bypass
At the top right, the down arrow button does not always work. It does not matter when I am setting the time of the day because I can always advance it through the 24 hour period to get it right, but when I am setting the amount of minutes, it is critical. If the minute timing goes to 8 minutes and I want to get it back to 4, it will not go back. Is there a way to replace just that portion somehow, or do I need to get an entire new unit?
A shopper on Aug 6, 2016
BEST ANSWER: Unfortunately I think you're just going to have to change that unit out because it's definitely circuitry
How to Set watering for Monday, Wednesday and Saturday?
Harry H on Jun 15, 2015
BEST ANSWER: Locate the middle button on bottom of the face plate. Slide to middle for settings. As you then turn the dial from current time, counter clockwise, to each day, push the plus button on upper right of the face plate for the days desired. Then turn the dial back to current time and switch the sliding button to the right to run.
Why does the water not shut off?
A shopper on May 11, 2015
BEST ANSWER: That is generally the valve in the ground not closing due to being old, or sometimes sand stick inside if using well water, or dirt and debri if using irrigation water from canals or ditches. I have never yet found this problem to be in the timer itself in all the 37 years of doing lawn care for others.

Why does it run through the cycle a second time?
Fred M on Apr 15, 2014
BEST ANSWER: I've never seen this happen with my unit. I'm sure you've checked but I'd be sure that the starting times are correct by flipping the A, B, C switch just to be certain that you don't have a second start time. If that doesn't work I'd unplug and take the 9 volt battery out... leave power off for a number of minutes and then power up and completely reprogram from square one. Maybe that will solve any existing glitches.
which direction to turn the Dial to select the valve number?
Carmen L on Oct 25, 2013
BEST ANSWER: Turn the dial clockwise and stop at the desired valve number. Turn the dial counter-clockwise to vertically align the arrows after you have made your changes.
Have this unit and it is not working. I get the letters FUS and it seems to not be communicating with the valves.
Yes this is a question?
t f on Oct 11, 2013
BEST ANSWER: Check your power wires. Mine said the same thing. I had too many wires going into the timer for power . Retraced the power wires and took out some that weren't doing Anytging and it worked fine.
I have the RD-600 model that is about 15 years old. Can I just uplug the old unit and plug the ribbon cable right into this one and keep my existing housing?
Roscoe R on Feb 24, 2013
BEST ANSWER: I just had to replace mine that went bad after about 10 years. I'm not sure if you can just reuse the housing, but it's really easy to replace the entire unit.
Is there a replacement electrical plug for this item ?
A shopper on Apr 13, 2012
BEST ANSWER: The unit came with a new plug. It was easy to connect. I made a drawing of my old set (by color and noted thetwo power lilne locations before disconnecting so the zones would be in the same order and properly wired. Doing it myself saved me $250 from what my service quoted.
My 5 IRRITROL 2711DPR chatter when running will replacing my Irritrol Rain Dial RD-600 with a new IRRITROL RD600-INT eliminate the chatter?
CARL F on Jul 31, 2018
I had this system for awhile and about 4 months ago 1 of the 4 settings stopped working. And now two of the settings are no longer functional. These 2 sections are in the back and close to each other, so I was able to switch the black box on the sprinkler outside from one to the other which worked until last week. We re-taped the wires today but still nothing. When turned on manually the screen reads FUS and then says off, never even turning on. How do I make these sections functional again? Help Please!
Charlene G on Jun 27, 2018
BEST ANSWER: check the fuse, if it is in good shape then it's time for a " hard reset " - disconnect the ribbon cable, disconnect the battery, set program to " B ", set mode switch to " Set Program ", hold down manual button while reconnecting the ribbon cable. If this doesn't clear the problem, call a professional for troubleshooting
